constrained_window code and updated some callers, but not the tab-modal
signin flow. The modal was being created but not shown.

Hi Robert, can you please take a look at this small fix?

This doesn't seem to be the only call site that CL broke (there's at least one
other similar fix today in the bug report). I'll try to see if there are
potential others.

Thanks!
